Product Description of 2-DODECEN-1-YLSUCCINIC ANHYDRIDE CAS#26544-38-7
Commonly abbreviated as DDSA, 2-Dodecen-1-ylsuccinic anhydride is a mainstream organic chemical compound, with a molecular weight of 266.38. It covers multiple standard CAS numbers including 25377-73-5, 26544-38-7 and 19780-11-1. Commercially, this product is available in two mainstream structural forms, namely linear dodecenyl succinic anhydride (LDDSA) and branched dodecenyl succinic anhydride (BDDSA).
The linear type is widely adopted as a durable epoxy resin curing agent and is well recognized as an excellent toughening agent for epoxy adhesive systems. Beyond epoxy resin applications, DDSA is extensively utilized for producing paper sizing agents, anti-rust additives, alkyd resin flexibilizers, leather treatment agents, plasticizers, ink additives, drying agents and polyvinyl chloride (PVC) stabilizers.

Product Application of 2-DODECEN-1-YLSUCCINIC ANHYDRIDE CAS#26544-38-7
2-Dodecen-1-ylsuccinic anhydride (DDSA) is a versatile toughening curing agent commonly applied in epoxy resin adhesives. It can be compounded with other anhydride curing agents to improve the overall performance of formula systems. This chemical has extensive industrial usability, serving as a key raw material for manufacturing paper sizing agents, oil antirust additives, alkyd resin flexibilizers, leather processing reagents, plasticizers and ink modifiers.
In the field of electronic packaging, DDSA acts as an efficient curing agent for epoxy resins. It greatly improves the water resistance, mechanical toughness, adhesive strength and electrical insulation of cured products. Furthermore, its hydrolyzed derivative, dodecenyl succinic acid, is regarded as a high-efficiency functional additive for oil-based antirust preparations.
